IMPROVEMENT l N DRAG-SAWING MACHINES.

Specification forming part of Letters Patent No. 219,366, datedSeptember 9, 1879 application filed July 1,

To all whom it may concern:

Be it known that I, BARNEY. Ross, of Bussell, in the countyof Wayne andState of Ohio, have invented a certain new and Improved Machine forSawing Logs, &c., of which the following is adescription, referencebeing had to the accompanying drawings, making a part of thisspecification, in which- Figure 1 is a side elevation of the machinewhen set for use. Fig. 2 is a plan view of the same. Fig. 3 is a sideview of the machine, partially in section, showing the machine with awheel attached thereto for transportation.

Like letters of reference refer .to like parts in the several views.

This invention relates to a portable machine for operating a saw forcross-cutting logs, sawing wood, &c., and which, when required to hemoved from place to place, is supplied with a wheel on which the machineis trundled by the operator. Said wheel is detached when the machine isagain to be set up for use. p

The application of a wheel to the machine for the purpose specifiedavoids the necessity of loading it into a wagon for moving it from oneplace to another.

A more full and complete description of the machine is as follows:

In the drawings, A, Fig. 1, represents an oblong rectangular frame,supported at the rear end by a pair of adjustable legs, B, secured inthe cross-tie or tail-piece (J by pins D, which also serve as handlesfor moving the machine, as hereinafter explained.

The front end of the frame is supported on a pair of legs, E, hinged tothe under side of the end of the frame. Said legs are retained inposition by braces F. By means of the hinge, by which the legs areattached to the frame, they can be turned up under the sides of theframe, as shown in Fig. 3.

On the top of each side of the frame is mounted an A-shaped frame, G,between which is hung a crank, H, having its hearings in the To one endof the shaft of the crank is secured a pinion, O, for operating the sameby means of a cog-wheel, I, engaging the pinion,

as shown in Fig. 2. On the opposite end of the crank-shaft is afly-wheel, I.

To the extremeupper end of one of the frames G is pivoted a lever, J. Tothe lower end of said lever is attached a connecting-rod, K, whereby thelever is attached'to the crank above alluded to 5 also, to the side ofthe frame G is pivoted a lever, L. The upper end of said lever L ispivoted to the upper end of the lever J, and moves conjointly therewith.The lower end of the lever J depends below the frame A, and is connectedto an arm, M, in which is secureda saw, N. Said arm is lifted upward forelevating the saw by means of a lever, 0, connected to said arm byacord, P, passing over the roller Q.

The position of the machine as shown in Figs. 1 and 2 is such as when itis in practi cal use. crosswise before the front end of the machineunder the saw, which is elevated by the lever and cord for that purpose.The log is held in place by a dogging-arm, B, projecting from the end ofthe machine.

The saw is operated by turning the cogwheel, thereby giving motion tothe pinion, which in turn operates the crank, and by its connection withthe lever J imparts a reciprocatin g action to the arm and saw, theweight of which feeds it to the log.

In order to move the machine from place to place, a wheel, B, Fig. 3, isplaced in the front end ofthe frame. kept in place by the front legs,which are turned up under the sides of the frame, and made fast theretoby any suitable means. The legs being relieved from supporting themachine, it is now'borne by the wheel, as shown in Fig. 3, on which theoperator can. wheel it off by lifting the rear end of the frame by thehandles D.

During the transportation of the machine the saw-arm and saw areelevated and se* cured in such position by a latch, to.

The machine is light in structure, and is easily managed by one personfor sawing and for moving it about.

What I. claim as my invention, and desire to secure by Letters Patent,is-

1. In portable machines for sawing logs, &c.,

To this end the log to be sawed is laid The axle of the wheel is thecrank H and gearings, levers J X L, connected to each at their upperends, and pivoted to the side of the frame G, pitman connecting saidcrank to the lever J, operating the lever L, to the lower end of whichis attached the arm M of the saw, in combination with the frame A,having adjustable rear legs and securing-pins, and the front legs,hinged to the under side of said frame to admit of their being turnedup, and to serve as boxes for the wheel, substantially as described.

2. In machines for sawing logs, &c., the

frame A, having the front legs hinged to the under side thereof, toadmit of their being turned thereunder, so as to form journal-boxes forthe Wheel B, adapted to run upon the ground for moving the machine fromplace to place, in the manner substantially as described, and for thepurpose specified.
